Mishnah Pesachim 6

¹These things in [connection with] the pesah override Shabbat: its slaughtering and the sprinkling of its blood and the cleansing of its innards and the burning of its fat. But its roasting and the washing of its innards do not override Shabbat. Carrying it and bringing it from outside the Shabbat border and cutting off its wart do not override Shabbat. R. Eliezer says they do override [Shabbat]. ²Rabbi Eliezer said: is it not logical: if slaughtering, which is [usually forbidden] as a labor, overrides Shabbat, shouldn’t these, which are [only forbidden] as mandated rest (shevut), override Shabbat? Rabbi Joshua said to him: let the festival prove this, for they permitted labor [on the festival] and forbade [activities forbidden because of] shevut. Rabbi Eliezer said to him: what is this, Joshua? What proof is a voluntary act in respect of a commandment! Rabbi Akiva answered and said: let sprinkling [purificatory waters] prove it, which is [performed] because it is a commandment and is [forbidden only] as a shevut, yet it does not override Shabbat; so you too, do not wonder at these, that though they are [required] on account of a commandment and are [forbidden only] as shevut, yet they do not override Shabbat. Rabbi Eliezer said to him: but in respect of that I am arguing: if slaughtering, which is a labor, overrides Shabbat, is it not logical that sprinkling, which is [only] a shevut, should override Shabbat! Rabbi Akiva said to him: or the opposite: if sprinkling, which is [forbidden] as a shevut, does not override Shabbat, then slaughtering, which is [normally forbidden] on account of labor, is it not logical that it should not override Shabbat. Rabbi Eliezer said to him: Akiva! You are uprooting what is written in the Torah, “at twilight, offer it at its set time” (Numbers 9:3), both on week-days and on Shabbat. He said to him: master, give me an appointed time for these as there is an appointed season for slaughtering! Rabbi Akiva stated a general rule: work which could be done on the eve of Shabbat does not override Shabbat; slaughtering, which could not be done on the eve of Shabbat, does override Shabbat. ³When does he bring a hagigah with it [the pesah sacrifice]? When it comes during the week, in purity, and in small [amounts]. But when it comes on Shabbat, in large [amounts], and in impurity, one does not bring the hagigah with it. ⁴The hagigah was brought of flocks, herds, lambs or goats, of the males or the females. And it is eaten two days and one night. ⁵If the pesah was slaughtered for a different purpose on Shabbat, he [the slaughterer] is liable to a sin-offering on its account. All other sacrifices which he slaughtered as a pesah: if they are not fit [to be a pesah] he is liable; if they are fit [to be a pesah]: Rabbi Eliezer makes him liable to a sin-offering, But Rabbi Joshua exempts him. Rabbi Eliezer said to him: if for the pesah, which it is permitted [to slaughter] for its own purpose, yet when he changes its purpose he is liable; then [other] sacrifices, which are forbidden [to slaughter even] for their own purpose, if he changes their purpose is it not logical that he should be liable. Rabbi Joshua said to him: not so. If you say [with regard to] the pesah, [he is liable] because he changed it to something that is forbidden; will you say [the same] of [other] sacrifices, where he changed them for something that is permitted? Rabbi Eliezer said to him: let the community sacrifices prove it, which are permitted for their own sake, yet he who slaughters [other sacrifices] in their name is liable. Rabbi Joshua said to him: not so. If you say [with regard to] the public sacrifices, [that is] because they have a limit; will you say [the same] of the pesah, which has no limit? Rabbi Meir says: he too who slaughters [other sacrifices] in the name of public sacrifice is not liable. ⁶If he slaughtered it for those who are not its eaters, or for those who were not registered for it, for uncircumcised or for unclean [persons], he is liable. [If he slaughtered it] for its eaters and for those who are not its eaters, for those who are registered for it and for those who are not registered for it, for circumcised and for uncircumcised, for unclean and for clean [persons], he is exempt. If he slaughtered it, and it was found to possess a blemish, he is liable. If he slaughtered it and it was found to be an internal terefah, he is exempt. If he slaughtered it, and [then] it became known that its owners had withdrawn their hands from it, or that they had died, or that they had become unclean, he is not culpable, because he slaughtered it with permission.
